6707 Shigeru           Discovered 1988 Nov. 13 by M. Yanai and K. Watanabe at Kitami.
Named in honor of Shigeru Nakano (b. 1918), doctor of medicine specializing in obstetrics and gynecology and in medical jurisprudence. An amateur astronomer, he has published many observational guidebooks and star atlases, including the most detailed one in Japan. Name proposed by the discoverers following a suggestion by A. Fujii and T. Sato.
